In this reaction, the boryl group in the generated organoborane is substituted with a hydroxyl group. The peripheral chemoreceptors are significantly activated when the PO2 decreases to about A. For example, the primary product of the reaction of diborane with ammonia is boranylium boranuide diammoniate, which is isolatable. By using iodine as the oxidant, it is possible to eliminate the production of diborane as an intermediate, as done in the production of the THF adduct. 21 - Write balanced equations for the reaction of...

The magnitudes of two vectors A and B are 12 units and 8 units, respectively. The carbon–nitrogen double bond is created by the reductive elimination of water from a hemiaminal, formed by the addition of an amine to a carbonyl molecule, hence the adjective 'reductive'. Hint: Nitrogen has seven protons. When desolvating borane, it is necessary to maintain a low concentration, due to its propensity to dimerise. 21 - A sulfuric acid plant produces an enormous amount...
